"The future of Fernando Llorente is in black and white," a statement on the club's official website read.

"The Spain international, who will be out of contract with Athletic Bilbao, has signed an agreement that will bind him to Juventus from July 1.

"The contract lasts for four years, expiring on June 30, 2017."

Juventus have long been looking for a striker to bolster their attack, with the likes of Alessandro Matri, Sebastian Giovinco, Fabio Quagliarella and Mirko Vucinic failing to impress on a consistent basis.

Llorente made his debut for Athletic in 2004, and has since made over 350 appearances for the club. He was part of the side that reached the Copa del Rey and Europa League finals last season.
